CVE-2025-14274: Unlimited Elements Elementor XSS Flaw

CVE-2025-14274 Overview

The Unlimited Elements for Elementor plugin for WordPress is vulnerable to Stored Cross-Site Scripting (XSS) via the Border Hero widget's Button Link field in versions up to 2.0.1. This vulnerability stems from insufficient input sanitization and output escaping on user-supplied URLs. Authenticated attackers with Contributor-level access or above can inject arbitrary web scripts into pages that execute whenever a user accesses the affected page.

Critical Impact

Authenticated attackers can inject persistent malicious JavaScript through the Border Hero widget, potentially leading to session hijacking, credential theft, and defacement of WordPress sites using the Unlimited Elements for Elementor plugin.

Affected Products

• Unlimited Elements for Elementor plugin for WordPress versions up to 2.0.1
• WordPress installations utilizing the Border Hero widget component
• Sites with Contributor-level or higher user accounts enabled

Technical Details for CVE-2025-14274

Vulnerability Analysis

This Stored Cross-Site Scripting vulnerability exists within the Border Hero widget's Button Link field processing logic. The plugin fails to properly sanitize and escape user-supplied URL input before rendering it in the page output. When a user with Contributor-level access or above creates or edits content using the Border Hero widget, they can inject malicious JavaScript code through the Button Link field.

The vulnerability is classified as CWE-79 (Improper Neutralization of Input During Web Page Generation). The attack requires network access and user interaction (a victim must view the injected page), but the persistence of the injected script means it affects all subsequent visitors to the compromised page. The scope is changed, meaning the vulnerability can impact resources beyond the vulnerable component itself.

Root Cause

The root cause is insufficient input sanitization and output escaping in the plugin's URL handling functions. According to code review references, the vulnerable code path involves the parameter processor class (unitecreator_params_processor.class.php) and the framework functions (functions.class.php). User-supplied URLs passed through the Button Link field are not adequately validated or escaped before being rendered in the HTML output, allowing JavaScript code embedded in the URL to execute in the browser context.

Attack Vector

The attack vector requires authenticated access at the Contributor level or higher. An attacker would:

1. Authenticate to the WordPress site with Contributor or higher privileges
2. Create or edit content using the Unlimited Elements for Elementor plugin
3. Add a Border Hero widget to the page
4. Insert malicious JavaScript payload in the Button Link field
5. Publish or save the content

Once the malicious content is saved, any user who views the page will have the injected script execute in their browser. This can lead to session cookie theft, keylogging, phishing overlays, or redirects to malicious sites.

The vulnerability mechanism involves improper handling of URLs in the Border Hero widget component. The Button Link field accepts user input that is not properly sanitized before being rendered in the page output. Technical details can be found in the WordPress Function Code Review and WordPress Parameter Processor Code.

Detection Methods for CVE-2025-14274

Indicators of Compromise

• Unusual JavaScript code or javascript: protocol URLs in Border Hero widget Button Link fields
• Unexpected <script> tags or event handlers within Elementor content blocks
• User reports of browser warnings or unexpected redirects when viewing specific pages
• Audit logs showing Contributor-level users editing pages with Border Hero widgets

Detection Strategies

• Review WordPress database for suspicious URL patterns in widget data, particularly javascript:, data:, or encoded payloads in Button Link fields
• Implement Web Application Firewall (WAF) rules to detect XSS patterns in POST requests to Elementor endpoints
• Monitor for unusual outbound connections or script loads from untrusted domains on pages using the Border Hero widget
• Use content security policy (CSP) violation reporting to identify unauthorized inline script execution

Monitoring Recommendations

• Enable comprehensive WordPress audit logging to track widget content changes by user
• Deploy browser-based XSS detection tools or security plugins that monitor for DOM manipulation
• Regularly scan page content for known XSS patterns and obfuscated JavaScript
• Monitor user activity for Contributor accounts creating or modifying Border Hero widget content

How to Mitigate CVE-2025-14274

Immediate Actions Required

• Update the Unlimited Elements for Elementor plugin to the latest patched version immediately
• Audit existing content using the Border Hero widget for malicious URL patterns
• Review user accounts with Contributor-level access and revoke unnecessary privileges
• Consider temporarily disabling the Border Hero widget until the update is applied

Patch Information

A security patch addressing this vulnerability is available. Review the WordPress Changeset for technical details on the fix. The patch implements proper input sanitization and output escaping for URL fields in the Border Hero widget. Users should update to a version beyond 2.0.1 through the WordPress plugin update mechanism.

For additional vulnerability information, refer to the Wordfence Vulnerability Advisory.

Workarounds

• Restrict Contributor-level access to only trusted users until the plugin is patched
• Implement a Web Application Firewall with XSS filtering rules for WordPress admin and AJAX endpoints
• Use Content Security Policy headers to block inline script execution on public-facing pages
• Temporarily remove or disable the Border Hero widget from the available Elementor widgets

# Configuration example - Add CSP header to WordPress .htaccess
<IfModule mod_headers.c>
    Header set Content-Security-Policy "script-src 'self' https://trusted-cdn.com; object-src 'none';"
</IfModule>
